They better do, otherwise all the tech put into XBX will be basically wasted and used only in a bunch 1st party titles (unless automatically being utilized without devs interference). But reading how many custom hardware-based features are build into that 360mm chip, and furthermore is backed up by Microsoft's proprietary software solutions, I can see Sony going with a more simple, but still powerful system, like the rumored 14-15TF, which would be more beneficial for all the 3rd party titles out there, because it would be accessible just like that, without any effort.
USB 3.2 Gen 1 already offers 5Gbps bandwidth, Gen 2 10Gbps, Gen 2x2 20Gbps, so even the base Gen 1 connection offers enough bandwidth for XBX SSDs, so that's not the issue, the problem is the drives themselves, how many of them offer (steady) 2.4Gbps bandwidth? IMO it's a good move from MS to secure the integrity of the solution, otherwise I can see shitloads of people cheaping out with a typical 1-1.5Gbps drives, or SATA SSDs for the matter, or even old HDDs like I can already read in lots of the comments... And the best part? They would blame the console/MS if something wasn't working well.
But the funniest thing is, it was such an awesome idea back when it was rumored what Sony was going to do for PS5, but once it turn out it's MS who actually pulled it out for XBX it's all of a sudden a terrible, anti-consumer practice xD People don't have the console yet, didn't even start filling the build-in 1TB drives (with said build-in compression), and are already moaning about a theoretical issue that doesn't exist... Get a life some of you pathetic nerds, for real...
